fix: quote variables and use zsh idioms in shell config

- Quote ZINIT_HOME in plugin manager setup
- Quote $1 in mkcd function
- Use [[ ]] instead of [ ] in yazi wrapper (zsh idiom)
- Remove double blank line in .vimrc

-# dotfiles
-
-Bare-git managed dotfiles for zsh/vim/tmux on Linux and macOS.
-
-## How it works
-
-This repo uses a **bare git repository** at `~/.dotgit` with the work tree set to `$HOME`. This avoids symlinks and lets dotfiles live at their native paths.
-
-The alias that drives everything:
-
-```bash
-alias .g='git --git-dir=$HOME/.dotgit/ --work-tree=$HOME'
-```
-
-`.g status`, `.g add`, `.g diff`, `.g commit`, `.g push` — same as git, just scoped to the dotfiles repo. Untracked files are hidden by default (`showUntrackedFiles = no` in config).
-
-## Bootstrap on a new machine
-
-```bash
-git clone --bare https://gitea.abra.me/svxf/dotfiles.git $HOME/.dotgit
-alias .g='git --git-dir=$HOME/.dotgit/ --work-tree=$HOME'
-.g checkout
-.g config status.showUntrackedFiles no
-```
-
-If checkout conflicts with existing files, back them up first:
-
-```bash
-.g checkout 2>&1 | grep "^\t" | xargs -I{} mv {} {}.bak
-.g checkout
-```
-
-On next shell start, zinit will bootstrap itself and install all plugins automatically.
-
-## Tracked files
-
-| File | What it does |
-|---|---|
-| `.zshrc` | Shell config — plugins, aliases, functions, keybindings, PATH |
-| `.vimrc` | Vim config — space-leader, persistent undo, arrow keys disabled |
-| `.tmux.conf` | tmux config — mouse, green accent, fzf window switcher, auto-rename |
-| `.starship.toml` | Prompt — two-line, git status, docker indicators, command duration |
-| `.gitignore_global` | Global ignores — `*~`, `.DS_Store`, `__pycache__`, `.idea`, `.ipynb_checkpoints` |
-
-## Key features
-
-### Zinit plugin stack (`.zshrc`)
-
-- **zsh-autosuggestions** — inline fish-style suggestions
-- **zsh-syntax-highlighting** — live command coloring
-- **zsh-completions** — extra completion definitions
-- **zsh-history-substring-search** — up/down searches from prefix
-- **starship** — installed via zinit from GitHub releases
-
-### Async dotfiles pull
-
-On shell start, a background job pulls `--ff-only` from origin once per day (marker at `~/.cache/.dotfiles-pull`). Silent, non-blocking.
-
-### Starship prompt (`.starship.toml`)
-
-Two-line layout:
-- **Line 1**: docker container indicator → docker-compose status → git branch/status → (fill) → directory
-- **Line 2**: `➤` character (green=ok, red=error)
-- **Right**: command duration (>5s) → user@host → time
-
-Custom modules detect `/.dockerenv` for container awareness and parse `docker compose ps` for service status.
-
-### fzf integration (`.zshrc`)
-
-Sources fzf keybindings and completion when available. Default opts: `--height 40% --reverse`.
-
-### Project switcher — `pj` (`.zshrc`)
-
-Fuzzy-finds directories under `/projects` or `~/projects` using fzf. `pj foo` pre-fills the query.
-
-### Yazi wrapper — `y` (`.zshrc`)
-
-Wraps the yazi file manager so the shell `cd`s to wherever you navigated on exit.
-
-### Docker compose aliases (`.zshrc`)
-
-| Alias | Expands to |
-|---|---|
-| `,dcdu` | `docker compose --profile dev up service_dev --force-recreate --detach` |
-| `,dcdd` | `docker compose --profile dev down --remove-orphans` |
-| `,dcdl` | `docker compose --profile dev logs -f service_dev` |
-| `dcu` | `docker compose up --force-recreate --detach` |
-| `dcd` | `docker compose down --remove-orphans` |
-| `dcl` | `docker compose logs -f` |
-
-### Tmux aliases (`.zshrc`)
-
-| Alias | What it does |
-|---|---|
-| `tmuxr` | Attach-or-create session named "auto" |
-| `tmuxn` | Same + opens a new window |
-| `tmuxa NAME` | Attach-or-create a named session |
-
-### Tmux keybindings (`.tmux.conf`)
-
-- **Shift+Left/Right** — switch windows (no wrap)
-- **PgUp/PgDn** — swap window position left/right
-- **prefix+f** — fzf fuzzy window switcher
-- **prefix+R** — rename window
-- Splits retain current path. 1-indexed windows, auto-rename shows `command@directory`.
-
-### Vim (`.vimrc`)
-
-Space as leader. `jk` exits insert mode. Persistent undo in `~/.vim/undo/`. Arrow keys disabled (hjkl only). Mouse enabled. Smart case search. 8-line scroll margin.
-
-### Utility functions (`.zshrc`)
-
-| Function | Purpose |
-|---|---|
-| `clip` | Pipe stdin to system clipboard via OSC 52 (works over SSH/tmux) |
-| `mkcd DIR` | mkdir + cd in one step |
-| `cdtmp [label]` | Create and cd into a timestamped temp dir under `~/tmp/` |
-
-### Other aliases (`.zshrc`)
-
-- `c` → `claude`
-- `,cd` → `claude --dangerously-skip-permissions` (with sandbox flag)
-- `zshreload` → `exec zsh`
-- `LATEST` — global alias expanding to `*(om[1])` (most recently modified file)
-
-### Shell options (`.zshrc`)
-
-Extended history (100k lines, shared, deduped). Case-insensitive globbing. Auto-pushd on cd. No flow control (Ctrl-S disabled). Emacs keybindings with Ctrl+X,E / Alt+E for `$EDITOR`.
-
-### Machine-local overrides
-
-`~/.zshrc-extra` is sourced at the end if it exists — for per-machine config that doesn't belong in version control.
